Duplicate Finder - Retrieve and Remove Duplicate Files

By Trend Micro Incorporated

Open the Mac App Store to buy and download apps.


Stop cluttering your disk space with meaningless copies of files. With just one click, Duplicate Finder finds all duplicate files on your hard disk. It quickly scans your disk and clearly presents all the duplicates so you can selectively choose which to delete.

A newly added feature, "Photo Clean", helps you clean duplicate photos in the Photos Library!

Duplicate Finder is brought to you by the same team that created Dr. Cleaner. It features an easy-to-use drag and drop user interface and includes the following functions to keep your disk clean and organized:

• Thorough and selective scan — utilizes a fast and accurate scanning technique that scans your entire Mac. You can choose to scan your entire home folder or some specific folder(s).

• Smart and accurate selection — duplicate files are selected not only by file names, but also by their contents. Files are shown in detailed previews. You can also choose the "Auto Select" feature that recommends which copy to delete.

• Easy and safe decision — duplicates can be sorted by file type and listed with their full path for you to track to the original location. You can decide if they should be sent to Trash or permanently deleted.

Good tool for finding dupes

This is a great tool for finding duplicate files, even if the filenames are different. With over 50,000 image and movie files to consolidate from several backup disks, I needed help organizing the task, and this app did the job, well enough. Initial scans can be slow depending on the density of the analyzed files, but subsequent scans of the same folders is significantly faster. Stopping and restarting a scan is simple, even if you are in the middle of organizing your files. The preferences give you enough flexibility to manage the scanning target by folder location and filename, but I would add file type (‘kind’) as well to provide a wildcard option to narrow the scan search. The option to remove a file to a folder other than the Trash would also be helpful. Lastly, the interface could display a plan of action and time estimate after the first pass, allowing the user to alter the parameters in order to improve performance or reduce the processing time through changes in folder and file selection.

An Impressive App

In my use of the ‘Duplicate Finder’ application thus far, I’ve been quite impressed with its ability to conquer the largest hard-drives/file folder(s), and produce an accurate output of items to be deleted (with optional ‘auto=delete’ feature). Duplicate Finder is the best app of its kind time I’ve come across; my sole complaint is that sometimes it seems to get in a “spinning rainbow” death spiral toward the end of the ‘Delete’ function (stops at around "80%-90% completed" point) and/or when the app opens the OS X application “Photos” to delete any files found within the native Mac app. Nonetheless, 4 out of 5 stars!! I’m getting lots of use out of it.

In my case it seems to find the files but then it will not actually remove them...

When I perform a scan of my Personal Photos folder the program reveals that there are 1780 and it shows them on the left side of the window. When I hit “Auto Select” and then choose “Remove” (to trash) it removes approximately 10 images and the rest of the 1770 still show in that left side of the window. So, when I attempt to remove them again it seems to go through the process but then tells me that “0 B Files have been moved to trash” and offers no clue or option as to how to remove the files that it has found. Can anyone offer tip here or am I just out another ten bucks on another crappy app?
